sFRP-1 is necessary for ANE specification. Aae six3, foxq2, dkk3, nkx3.2, and sfrp-1/5 expression in mesenchyme blastula stage control embryos (24 hpf). Agk Embryos injected with sFRP-1 morpholino 1 show complete elimination of ANE markers. B qPCR measurements from three different cultures of embryos showing the downregulation of ANE regulatory genes at mesenchyme blastula stage (24hpf) in sFRP-1 morphants. The y axis shows the fold change in gene expression for sFRP-1 morphants versus controls. Scale bar = 20 μm. MO, morpholino
